Description
[0001] This application is a continuation application of U.S.
application Ser. No. 14/143,974, filed Dec. 30, 2013, which claims
the benefit of U.S. Provisional Application No. 61/747,635 filed
Dec. 31, 2012, and U.S. Provisional Application No. 61/913,618
filed Dec. 9, 2013.
FIELD OF THE INVENTION
[0002] The invention relates to a modular cover for support
structures having multiple cover segments connected together using
multiple connection techniques.
BACKGROUND OF THE INVENTION
[0003] Covers for support structures, such as columns, include
sleeves, shields, and wraps that cover the support structure. The
covers are for protecting a support structure of, for example, a
bridge or an overpass commonly located along roadways.
[0004] In areas where snow and ice accumulate, and the snow is
removed from the road by a snow plow or other snow removal device,
road salts, chemicals, and other materials incidentally adhere to
the support columns along the road. In many instances, the support
structures are made of concrete. As a result, erosion and
deterioration of the supports occurs necessitating major repair,
which is costly.
[0005] One preventative measure available to inhibit corrosion of
the concrete support is supplied by routine painting of the
supports. However, painting is expensive, poses a safety risk to
workers, and disrupts traffic in areas where the maintenance is
taking place. Also, the paint only lasts for a short period of
time. Accordingly, the painting process only assists in the
preventative maintenance, and becomes a continuous/recurring
procedure.
SUMMARY OF THE INVENTION
[0006] The modular cover for support structures having multiple
cover segments according to embodiments of the invention prevents
the deterioration of the support structure while protecting it from
the elements and chemicals mixed into precipitation. In particular,
the invention is directed to the prevention of concrete spalling
due to snow and chemicals (e.g., road salts) adhering to the
surface of the concrete, without affecting the structural integrity
of the bridge or overpass once the cover is installed. The cover
will accommodate supports of any height and any shape.
[0007] Thus, the apparatus aims to prevent catastrophic bridge
failures caused by the erosion of supports. The cover prevents the
support member from peeling, rotting, or absorbing water and the
cover therefore becomes resistant to salt corrosion.
[0008] The cover segments when connected together are aesthetically
appealing. The modular cover is easy to install, cost effective,
and environmentally friendly. The cover is lightweight, may be made
of recyclable/recoverable material (green technology), and reduces
safety issues/hazards that normally are associated with industry
standard maintenance practices, such as the painting along
roadways. Upon application of the present invention, road closures
would be less frequent and bridge support life cycles would be
longer.
[0009] It is an object of the present invention to provide a
modular cover that protects support structures from corrosion and
thereby overcome the drawbacks of the prior art. Further, it is an
object of the present invention to provide a modular cover made of
inexpensive material that a worker may install quickly and without
difficulty. It is another object of the embodiments of the
invention to provide modular cover that can be molded into shapes
and designs that fit multiple shapes of supports structures. It is
yet another object of the present invention to provide a cover that
is light-weight and durable. Another object of the present
invention is to provide vertical and lateral connecting features on
the cover segments that allow one cover segment of multiple cover
segments connected to form a cover to be uninstalled while leaving
the other cover segments of the cover installed.
[0010] It is yet another object of the present invention to provide
a modular cover for surrounding a support structure, including: a
plurality of cover segments modularly connected to form the cover;
lateral connectors formed on opposite sides of each cover segment
in the lateral direction; top grooves formed periodically into a
top flange member, which extends inwardly around the top surface of
each cover segment; bottom extending members extending in a
downward direction along a bottom surface of each cover segment;
and a plurality of contact members formed as an indentations in the
outer surface of each cover segment extending inward; wherein the
lateral connectors of one side of a cover segment connect to
corresponding lateral connectors formed on the opposite side of
another cover segment, the bottom extending members of a cover
segment fit into corresponding top grooves of another cover segment
when cover segments are stacked vertically to form the cover. The
cover segments are formed of high density polyethylene. On one side
of the cover segment the lateral connectors are formed as a
protruding member extending outwardly, and on the opposite side of
the cover segment, the lateral connectors are formed as an
accepting member for accepting the protruding member. Further, upon
connection, the lateral connectors form a mechanical connection.
The lateral connectors, top flange member, and bottom extending
members, are formed as one piece.
[0011] The cover segment further includes a bottom extending flange
member which extends in an inward direction around the bottom
surface of each cover segment, wherein the bottom extending members
are formed to extend in a downward direction off of the bottom
extending flange member, and upon vertical stacking of cover
segments to form the cover the bottom surface of the bottom
extending flange member contacts the top surface of the top flange
member. The lateral connectors on one side of the cover segment are
formed to have top and bottom concave surfaces, the lateral
connectors on the opposite side of the cover segment are formed to
have top and bottom concave surfaces and are formed to accept the
lateral connectors on the one side of a cover segment, the later
connectors on the one side of the cover segment and the lateral
connectors on the opposite side of another cover segment connect
such that a side edge of each cover segment connected is flush when
connected, and a flexible fastener is used to secure the connection
made between the lateral connectors, the flexible fastener is
guided by the top and bottom concave surface of the lateral
connector on the opposite side of the cover segment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0065] The modular cover for support structures according to
embodiments of the invention has multiple cover segments connected
together using multiple connection techniques. Although the
examples of the uses of the modular cover or cover apparatus refer
to covering support structures, which are column supports for a
bridge or an overpass, the invention is not limited to that use.
The cover may be adapted and modified to fit around structures of
many shapes and sizes. Additionally, the cover segments of the
modular cover may be injection molded, by standard plastic
manufacturing process methods & materials, such as
thermoforming, blow molding, compression, rotomold, and forms of
injection molded processes. The cover segments are preferably made
of high density polyethylene. The cover segments may be structured
according to the shape of the support structure to be covered,
e.g., a column of circular cross section. The present invention is
not limited to any of the mold process listed above.
[0066] FIG. 1 shows a modular cover or cover apparatus 2 according
to the first embodiment of the present invention. The cover 2 is
comprised of a plurality of cover segments 10 according to the
first embodiment that are connected to each other to cover a
support structure 1. The support structure 1 as referred to herein
is a bridge support column, pier, pillar, pole, abutment or any
other component used to support an overpass or a bridge, etc. The
figures show a cover 2 in a circular form configured to cover a
concrete support structure 1 that has a cylindrical shape. Although
the figures show the cover in a circular form to cover a structure
that has a cylindrical shape, the cover segments may be
manufactured to cover support structures of any shape, such as
rectangular, and the shape of the cover is not limited to that
shown in the figures.
[0067] The cover is modular in that segments 10 are connected
laterally (horizontally) together, and also vertically together
(stacked on one another) to cover a support structure in situ.
Preferably, the cover segments 10 are joined laterally in one
vertical layer. The vertical layer is lifted so that another
vertical layer of segments 10, which have been joined laterally
around the support 1, can be connected. The lifted vertical layer
is then lowered onto the lower vertical layer to connect in the
vertical direction. The vertical layers of the stacked modular
cover 1 are able to be continued to achieve a vertical stack of a
desired overall height.
[0068] FIG. 2 shows a pair of cover segments 10 that when laterally
joined cover a circular cylindrical support 1. Each of the segments
10 includes lateral connectors 50, support legs 30, support leg
slots 40, a plurality of stand offs 20, groove interconnector 70,
and tongue interconnectors 80. When cover segments 10 are connected
using the lateral connectors 50, support legs 30, support leg slots
40, groove interconnector 70, and tongue interconnectors 80, a
uniform cover 2 is provided that is impermeable to a precipitation
and resultant chemical mixture from the application of chemicals
(e.g., road salts) added to a roadway.
[0069] As shown primarily in FIGS. 1 and 2, a plurality of stand
offs or spacers 20 are formed in each cover segment 10. The stand
offs are arranged in evenly spaced intervals on the cover segment
10 about 60 degrees apart in one embodiment; however, the
arrangement may be adjusted according to the support structure 1
being covered.
[0070] The stand offs 20 are formed as a pocket molded inwardly
from the outer surface 3 of the cover segment 10 and as a result
extend inwardly toward the support structure 1 when the cover
segment 10 is installed. As a result of the formation, a stand off
pocket 22 is formed. The stand offs 20 function as spacers to keep
the cover 2 from being held in full contact with the surface of the
support structure 1. Additionally, as shown in FIG. 8, which is a
detailed view of the cross sectional view of FIG. 7 taken along
line 7-7 of FIG. 4, a gap 21 for tolerance of expansion may be
provided between the stand off 20 and the surface of the support
structure 1. The gap 21 allows for expansion of the support column
1 material (concrete) due to fluctuations in temperature, for
example. Accordingly, the stand offs 20 are not all in contact with
the support structure 1, and depending on the expansion state of
the support structure 1, a gap 21 may exist between the support
structure 1 and several of the stand offs 20.
[0071] Each cover segment 10 is provided with a plurality of
support legs 30 according to embodiments of the invention, which
are formed along the base or bottom portion 5 of the cover segment
10. FIGS. 1 and 2 show support legs 30 extending downwardly from a
bottom edge 34 of the segment 10 to make contact with the surface
of the ground or other area surrounding the support structure 1.
Additionally, support legs 30 provide a point of contact with the
area surrounding the support structure 1 that are suitable for
supporting the weight of the cover 2. Two support legs 30 per
segment 10 are shown in the drawings; however, additional support
legs 30 are possible for supporting a segment 10.
[0072] FIG. 1 shows the support legs 30 to have a square profile,
however the profile of the support legs 30 may alternatively be
tapered, pointed or curved at the ground engaging portion. An
additional function of the support legs 30 is to raise or elevate
the bottom portion 5 of the cover segment 10 so that a clearance 60
is provided between the bottom edge 34 and the area surrounding the
base of the support structure 1 to provide for space at the bottom
of the segment in which air can flow. At the top portion 4 of the
cover, air is also able to flow through channels 8. By permitting
air flow underneath the cover 2, between the cover 2 and the
support structure 1, and through the top portion 4, accumulation of
moisture is prevented. Additionally, the support legs 30 elevate
the cover segment 10 to enable a worker to inspect the integrity of
the support column 1 by viewing the support structure 1. For
example, visual observation is available for the detection of
spalling or defects. The clearance 60 created as a result of the
support legs 30 further allows a space for a worker to conduct
maintenance of the support structure 1. The support legs 30 also
provide an area for liquid, such as rain water, to escape.
[0073] FIG. 1 shows a first pair of segments 10 on which are
stacked a second pair of segments 10 to form a modular cover 2
having a total of four segments 10. Each cover segment 10 is
provided with a plurality of support leg slots 40 along a top
portion 4 of the cover. The support leg slots 40 are formed into
the outer surface 3 of the top portion 4 of each cover segment 10
and are formed into a shape that accepts the corresponding support
leg 30 of a vertically adjacent segment 10 when the segments 10 of
a second pair are stacked on top of a first pair, as shown in FIG.
1. Upon connection, the outer surface 3 of the support leg 30 of
the upper cover segment in FIG. 1 is flush with the outer surface 3
of the cover segment 10 below. It is apparent that the support legs
30 of one cover segment 10 align with the support leg slots 40 of
another cover segment in that the support legs 30 and the support
leg slots 40 are spaced at the same intervals. The support leg 30
and support leg slot 40 engagement when the cover segments 10 are
being stacked in the installation process, assists in the alignment
of the cover segments 10.
[0074] FIG. 9 is an enlarged detailed view of the area circled and
labeled in FIG. 7. FIG. 7 is a cross sectional view of a cover 2
taken along line 7-7 of FIG. 4. FIG. 9 shows the tongue 80 of an
upper stacked segment 10 engaged with the groove 70 of a lower
segment 10 of cover segments 10 that are stacked vertically. As
shown in FIG. 1, a plurality of groove interconnectors 70 are
formed on the top portion 4 of each cover segment 10. The groove
interconnectors 70 are arranged at intervals in alignment with the
corresponding tongue interconnectors 80, which are formed along the
bottom portion 5 of each cover segment 10. Groove interconnectors
70 are formed as J-shaped flanges that provide a groove opening
outwardly which accepts the corresponding tongue connectors 80
which are formed along the bottom edge 34 as shown in FIG. 1, for
example. This enables the tongue interconnector 80 of an upper
vertically adjacent cover segment to engage the groove
interconnector 70 of a vertically adjacent and lower cover segment
10 to connect the cover segments 10 together.
[0075] FIG. 9 shows a portion of the tongue interconnector 80 that
fits into the space provided by the groove interconnector 70 so
that the end portion of the tongue interconnector fits up against
the back of the groove, abutting upstanding flange portion 71 with
an appropriate tolerance for accommodating expansion and
contraction due to changes in temperature, for example. In this
way, the outer surface 3 of each cover segment 10 is even with each
other segment 10 so that the outer surfaces 3 of the segments are
flush with each other. The tongue interconnector 80 engages the
groove interconnector 70 such that the flat bottom portion 81 of
the tongue 80 engages the adjacent flat portion 72 of groove
interconnector 70, with appropriate tolerance, to provide a
connection between adjacent, vertically stacked cover segments 10.
Through the engagement of the groove interconnector 70 and tongue
interconnector 80, the stacked cover segments 10 are appropriately
aligned so that the so that the outer surfaces 3 of the segments 10
are flush with each other to provide an appearance that the
segments 10 form a continuous, essentially uninterrupted outer
surface to the eye of the observer.
[0076] Each cover segment 10 includes a plurality of lateral
connectors 50 formed on the sides 6A, 6B of each cover segment 10.
The lateral connectors 50 are arranged to align with corresponding
lateral connectors 50 and connect in their respective ways and
according to the following descriptions of the embodiments.
[0077] FIG. 4 shows a different view of the cover 2 shown in FIG. 3
and FIG. 5 is a cross section of FIG. 4 across the 5-5 line. The
cover segment 10 of the first embodiment includes a plurality of
connector tabs 51 and a plurality of tab receivers 52, constituting
lateral connectors 50, formed into the cover segment 10. The
connector tabs 51 are formed on one side (6B in FIG. 2) of a cover
segment 10 and tab receivers 52 are formed on the opposite side (6A
in FIG. 2) of a cover segment 10. FIG. 2 shows two cover segments
10, which are not connected; while FIG. 1 shows the cover segments
10 connected to form a cover 2 of the present invention. Sliding
the connector tabs 51 on one cover segment 10 into the tab
receivers 52 of another cover segment 10 makes a lateral
connection. As shown in FIG. 2, the tab receivers 52 of side 6A of
the cover segment 10 are configured to receive the connector tabs
51 of side 6B of another cover segment 10.
[0078] Upon connection, as shown in FIG. 1, the faces of the edges
of each side 6A, 6B contact and abut each other to form a seam in
the cover 2. However, the integrity of the cover 2 is not
diminished as a result of the seam.
[0079] As shown in FIG. 6, when the connector tab 51 and tab
receiver 52 are connected only the tab receiver 52 is visible on
the outside. The connector tab 51 and tab receiver 52 are formed to
extend outward from the outer surface 3 of the cover segment
10.
[0080] The shape of the connector tab 51 is structured to
correspond with the shape of the tab receiver 52 so that the
connector tab 51 fits in the tab receiver 52. In particular, the
top concave portion 53A of the tab receiver 52 is shaped to
correspond to the top concave portion 55A of the connector tab 51.
Additionally, the bottom concave portion 53B of the tab receiver 52
is shaped to correspond to the bottom concave portion 55B of the
connector tab 51. As a result of this configuration, the connector
tab 51 fits firmly inside the tab receiver 52. The lateral
connectors 50 of each embodiment provide for appropriate tolerance
for accommodating expansion and contraction due to changes in
temperature, for example.
[0081] FIG. 10 shows a flexible fastener 54, which is preferably a
zip-type tie. Upon connection of the cover segments 10 according to
the first embodiment, the fastener 54 is placed around the tab
receiver 52 and fastened to maintain the connection of the tab
receiver 52 and connector tab 51. The top surface of the top
concave portion 53A and bottom surface of bottom concave portion
53B of the tab receiver 52 guide the fastener 54 and provides for a
notch-type area for the fastener 54 to be placed.
[0082] The cover segment 10 of the second embodiment of the present
invention includes lateral connectors 50 of another configuration.
FIGS. 13 and 15 show connector blocks 110, which are fastened using
a sleeve 100. A plurality of connector blocks 110 are provided on
the sides 6A, 6B of each cover segment 10. The connector blocks 110
are preferably formed in a block or cube type shape and extend
outward from the outer surface 3 of the cover segment 10. As shown
in FIGS. 13 and 15, a stop block 111 is provided on each connector
block 110 to engage the sleeve 100. A C-shaped sleeve 100 is shown
in FIGS. 14A and 14B which has 4 faces and is shaped to slide down
the connector blocks 110 to maintain the connection of the cover
segments 10. Sleeve notches 112 are formed to accept the open face
of the sleeve 100.
[0083] The open ended face of the sleeve 100 faces the cover and
slides down through sleeve notches 112 formed into each connector
block 110. The sleeve notches 112 accept the opposing open ends of
the sleeve 100 and allow the sleeve 100 to slide down and engage
stop blocks 11. The faces of the connector blocks 110 contact and
abut each other when the sleeve 100 is in place, as shown in FIG.
15.
[0084] Third embodiment includes yet another form of lateral
connectors 50 of the present invention. Each cover segment 10 has a
plurality of flange portions 120 for joining cover segments 10 in
the lateral direction. As shown in FIGS. 16 and 18, the flange
portions 120 extend outward from the outer surface 3 of cover
segment 10 and are provided on the sides 6A, 6B of each cover
segment 10. Upon connection of the cover segments 10 in the lateral
direction to form a cover 2, the flange portions 120 of respective
cover segments 10 become aligned and abut each other so that the
respective faces of the flange portions 120 contact each other. The
faces of the flange part 123 are substantially flat and are formed
substantially perpendicular to the outer surface 3 of the cover 10.
Further, upon abutment the faces of the flange part 123 appear even
and flush to an observer.
[0085] As shown in FIG. 18, a shoulder portion 121 and a tie notch
are formed into each flange portion 120. Flange portions 120 are
provided with a tapered outer portion 124 that is useful for
accepting a band 130 which can be fit around the outer most end of
the tapered portions 124, expand over the shoulder portions 121 and
become seated to encircle the flange portions 120 for retaining the
flange portions 120 in abutment with one another.
[0086] The band 130 functions to keep the face of the flange parts
123 in contact. In other words, the band 130 maintains the lateral
connection between the substantially flat face of the flange part
123 and as a result, maintains the connection of the cover segments
10 to form a cover 2. The band 130 is preferably a stretch band,
which allows for relative expansion due to changes in temperature
caused by weather changes, for example. The band 130 includes an
opening 131 to fit around the flange portions 120 and may be made
of a flexible material, such as rubber.
[0087] FIG. 19 shows the lateral connectors 50 of the fourth
embodiment of the present invention. On each side 6A, 6B of the
cover segment 10 are disposed a plurality of overlying parts for
securing the cover segments 10 to an adjacent cover segment 10 in
the lateral direction (or for securing opposite sides 6A, 6B of the
cover segment so they connect).
[0088] FIG. 21 shows a cross section taken along 21-21 of FIG. 20
of the cover segment 10 of the fourth embodiment showing cap part
141 and concave shaped structure 140. At one end, a concave shaped
structure 140 has a shell 148 with a shoulder step flange 142 that
fits within a cap part 141, through the open cavity of cap part
141. The concave shaped structure 140 has a living hinge (not
shown) that provides rotation of the shell 148 about hinge line
146. When the shell 148 swings down 90.degree. from the position
shown in FIG. 22 to be in line with the cover segment 10, the cap
141 fits over the shell 148 to securely fasten the concave shaped
structure 140 and cap part 141 together. As shown in FIG. 23, the
cap 141 has a terminal flange 144 that engages the step flange 142
and is kept in the position by a bias force applying area 145 that
is preferably molded into the cap part 141. Upon connection of the
concave shaped structure 140 and the cap part 141, the edges 143A
and 143B of the cover segment abut each other evenly and are flush
to an observer.
[0089] Each of the cover segments 10 of the embodiments of the
present invention may be shaped to correspond to the shape of the
support structure. FIG. 2. shows two cover segments 10 that are
each shaped in 180.degree. semi circles to form a cover, when
connected, around a support column 1 that has a circular cross
section. However, the cover segments 10 may be shaped to form
around a column or post with n (n is an integer) number of flat or
curved faces. As an example, the cover segments may be shaped to
form a cover around a support structure which has a cube, box, or
square type structure that has 4 flat faces.
[0090] Another example of the shape of a support structure that the
cover segments of the present invention may be shaped to cover is
one that has two flat opposing sides and two curved opposing sides.
In this example, a combination of linearly shaped cover segments
and curve shaped cover segments are connected to form a cover
according to the techniques herein described.
[0091] Additionally, the present invention allows for the module
connection of cover segments of varying lengths (as measured form
one side 6A to the other 6B). For example, FIGS. 11A and 11B show a
cover segment 10 may be formed in a 120.degree. segment (which has
a length shorter than a 180.degree. cover segment) and FIGS. 12A
and 12B show a cover segment 10 may be formed in a 90.degree.
segment (which has a length shorter than a 120.degree.
segment).
[0092] The outer surface 3 of each cover segment 10 may also be
customized with a variety of profiles and textures for aesthetic
appeal. For example, the outer surface may resemble brick, stone,
or concrete. The outer surface 3 may be any color and preferably a
color that suits its environment.
[0093] The cover segments 10 and components (except for sleeve 100
and band 130) discussed above are also preferably molded using a
single mold so that the cover segment is formed to be one piece
that includes the lateral connectors 50 and vertical connecting
techniques. The components may also be separately manufactured and
added to a cover segment.
[0094] Described next are embodiments of devices and processes for
installing the cover 2 of the present invention. Cover segments 10
are first connected laterally using any of the lateral connection
techniques described in the embodiments of the present invention.
For reference, the connection of cover segments 10 in the lateral
direction around a support column 1 will be referred to herein as
an assembly of cover segments 10. In order to cover the vertical
span of a support column 1, multiple assemblies are stacked
vertically (in layers) to a desired height.
[0095] FIG. 24 shows cover segments 10 connected to form an
assembly (laterally connected cover segments 10) in a first
position. One or more vertical jacks 160 are provided to lift an
assembly to a second position shown in FIG. 26. The vertical jacks
160 may be used to lift or lower any of the combination of the
cover segments 10 described above. Additionally, the vertical jacks
160 are portable and capable of raising and lowering multiple
assemblies that have been vertically staked on top of one
another.
[0096] One embodiment of a vertical jack 160 is shown in FIG. 25
and is provided with a base 165 that supports a jack shaft
structure 168. The jack shaft 168 is connected to a base 165 by a
base bracket 161. The support jack 160 is also provided with a
crank mechanism 163, which is connected to the jack shaft 168 by a
crank mechanism bracket 167. The crank mechanism 163 may include a
winch mechanism provided to crank a cable 169 which is attached at
one end to a jack stand off insert 166. The other end of the cable
169 is attached to a spool of the crank mechanism 163 as it goes
through a pulley 162, which is provided on top of the vertical jack
shaft 168. As shown in FIG. 24, one end of the jack stand off
insert 166 is inserted into a stand off pocket 22 of a cover
segment 10. The opposite end of the jack stand off insert 166 fits
into and is guided by a track inside of the jack shaft 168. The
track spans vertically along the jack shaft 168 and allows the jack
stand off insert 166 to move in the vertical direction.
[0097] The jack stand off insert 166 is shaped to fit into the
stand off pocket 22, which is molded inwardly from the outer
surface 3 of the cover segment 10 to form a stand off 20.
Accordingly, the jack stand off insert 166 is of a shape and
structure corresponding to the stand off pocket 22. Upon inserting
the jack stand off insert 166 into the stand off pocket 22 of the
cover, the assembly is ready to be raised by a worker by using the
crank mechanism 163 to install another vertical layer of cover
segments below the initial cover assembly, which is in the second
position as shown in FIG. 26. Upon lifting the initial assembly to
a desired position, one or more a pole supports 170 are inserted
into an available stand off pocket 22 (i.e., not used by a vertical
jack). A pole support 170 is inserted by a worker and maintains the
raised position of the initial assembly in a reliable manner, for
safety, for example. Additionally, the pole supports 170 are
capable of supporting more than one layer of vertically stacked
assemblies.
[0098] As shown in FIG. 28, a base 172 and pole stand off insert
173 are connected to the pole support shaft 174 using a suitable
fixed, pivoted or fixable hinged connection, such as by welding or
using a threaded fastener. While the pole support shaft 174 is
shown to be used at an angled position with respect to the vertical
direction, the pole may be set in a substantially vertical
position. In order to secure the pole stand off insert 173 firmly
fitted into a stand off pocket 22, a fastening member may be
attached therebetween or a cable secured around the periphery of
the cover assembly linking several poles together.
[0099] FIG. 29 shows another assembly of cover segments 10
installed under the initial assembly which is raised in the second
position. The jack stand off insert 166 of the vertical jack 160 is
inserted into a stand off pocket 22 of the lower assembly as the
pole support 170 supports the above layer. The lower assembly is
then raised with the vertical jack 160 to engage the above assembly
in the manner described above. In the alternative, the jack stand
off insert 166 of the vertical jack 160 may be inserted into the
stand off pocket 22 of the above assembly and then lowered to
engage the assembly inserted below after the pole support 170 has
been removed.
[0100] FIG. 30 shows the above and below cover assemblies raised
using vertical jack 160 (only one of which is shown for clarity).
As shown, the jack stand off insert 166 is inserted into a stand
off pocket 22 of the lower assembly. A worker then cranks the crank
mechanism to raise the lower assembly, and thereby all assemblies
stacked on top, to a desired height to add an additional assembly
below, if necessary.
[0101] The vertical jack and the pole supports are also useful for
disassembly of the modular cover of the embodiments of the present
invention.
[0102] FIG. 31 shows a modular cover or cover apparatus 2 according
to yet another embodiment of the present invention. The cover 2 is
comprised of a plurality of cover segments 10 that are connected to
each other to cover a support structure 1. The support structure 1
as referred to herein is a bridge support column, pier, pillar,
pole, abutment or any other component used to support an overpass
or a bridge, for example. The figures show a cover 2 in a circular
form configured to cover a concrete support structure 1 that has a
cylindrical shape. Although the figures show the cover in a
circular form to cover a structure that has a cylindrical shape,
the cover segments may be manufactured to cover support structures
of any shape, such as rectangular, and the shape of the cover is
not limited to that shown in the figures.
[0103] The cover is modular in that segments 10 are connected
laterally (horizontally) together, and also vertically together
(stacked on one another) to cover a support structure in situ.
Preferably, the cover segments 10 are joined laterally in one
vertical layer. The vertical layer is lifted so that another
vertical layer of segments 10, which have been joined laterally
around the support 1, can be connected underneath the lifted
vertical layer. The lifted vertical layer is then lowered onto the
lower vertical layer to connect in the vertical direction. The
vertical layers of the stacked modular cover 1 are able to be
continued to achieve a vertical stack of a desired overall
height.
[0104] When cover segments 10 are connected using the below
described connections, a uniform cover 2 is provided that is
impermeable to a precipitation and resultant chemical mixture from
the application of chemicals (e.g., road salts) added to a
roadway.
[0105] Each of the cover segments 10 of the embodiments of the
present invention may be shaped to correspond to the shape of the
support structure. FIG. 31. shows three cover segments 10 that are
each shaped in 120.degree. segments to form a cover, when
connected, around a support column 1 that has a circular cross
section. However, the cover segments 10 may be shaped to form
around a column or post with n (n is an integer) number of flat or
curved faces. As an example, the cover segments may be shaped to
form a cover around a support structure which has a cube, box, or
square type structure that has 4 flat faces.
[0106] Another example of the shape of a support structure that the
cover segments of the present invention may be shaped to cover is
one that has two flat opposing sides and two curved opposing sides.
In this example, a combination of linearly shaped cover segments
and curve shaped cover segments are connected to form a cover
according to the techniques herein described. Additionally, the
present invention allows for the module connection of cover
segments of varying lengths. For example, a cover segment 10 may be
formed in a 180.degree. segment or formed in a 90.degree. segment
(which has a length shorter than a 120.degree. segment).
[0107] The outer surface 3 of each cover segment 10 may also be
customized with a variety of profiles and textures for aesthetic
appeal. For example, the outer surface may resemble brick, stone,
or concrete. The outer surface 3 may be any color and preferably a
color that suits its environment. FIGS. 31 and 32B show an example
of a brick pattern on the outer surface 3 of each cover segment 10.
While explaining the following embodiment of the cover segment 10,
there are similarities to the above described embodiments, which
are apparent, and therefore those descriptions are not
repeated.
[0108] The cover segments 10 and components discussed above are
also preferably molded using a single mold so that the cover
segment is formed to be one piece that includes the lateral
connectors 250 and vertical connecting techniques. Those having
ordinary skill in the art also understand that the vertical and
horizontal connecting components may be separately manufactured and
added to a cover segment instead of using a single mold. Further,
the cover segments of the below described embodiment (FIGS. 24-30)
use the jack assembly described above in the same manner to install
the cover around the support column.
[0109] In FIG. 31, a total of six cover segments 10 are connected
to form a cover 2. Each cover segment has support legs 230, 231.
When a cover is constructed of a multiple cover segments 10 stacked
on top of each other in the vertical direction the support legs
230, 231 of the lower cover segments support the cover segment 10
of the cover segments 10 above it. The support legs 230, 231 of the
lowest cover segment contact the ground surface. As shown in the
illustration of the front and back side of a 120.degree. section
cover segment 10, the cover segment has three support legs
including a middle support leg 230 and side support legs 231. As
shown in FIG. 32A, each support leg 230, 231 is made of a double
ribbed 233 design for strengthening characterizes, although other
designs may be implemented to further improve the strength of the
support legs 230, 231. The support legs 230, 231 will be discussed
in more detail below.
[0110] Each cover segment 10 has a top interconnector member 270
formed into and along the top edge of the cover segment. The top
interconnector 270 extends inward and toward the support structure
1 to be covered at essentially a 90.degree. angle with respect to
the surface of the cover segment 10. As shown in FIGS. 32A and 32B,
the top interconnector 270 has middle and side grooves 272, 271,
respectively, for engaging with and fitting into an indentation in
each support foot 234, which is explained in more detail below.
Upon vertically connecting cover segments 10, shown in FIG. 31, the
top surface of the top interconnector 270 abuts with the lower
surface of the bottom extension 280 member.
[0111] The bottom extension 280 is formed along and into the bottom
edge of the cover segment 10. The bottom extension extends inward
and towards the support structure 1 to be covered at essentially a
90.degree. angle with respect to the surface of the cover segment
10. As shown in FIG. 32A, the bottom extension has a downward
extending flange 281, which extends in a downward direction at
essentially a 90.degree. angle with respect to bottom extension
280. As shown in FIG. 32A, the downward extending flange 281
extends from the bottom extension 280 along the bottom extension
280. In addition, the support legs 230, 231 include a support leg
downward extending flange 282 extending off and downward from each
support leg 230, 231.
[0112] A plurality of stand offs 221, 222 are formed in each cover
segment. The stand offs 221, 222 are formed as a pocket molded
inwardly from the outer surface 3 of the cover segment 10 and as a
result extend inwardly toward the support structure 1. The stand
offs 221, 222 function as a contacting point between the cover and
the outer surface of the support structure 1 being covered. As
shown in FIG. 32A, middle stand offs 222 have a slightly different
structure than side stand offs 221. The middle stand offs 222 have
a flange 227 extending in respective directions depending on the
position of the middle stand off 222 relative to the cover segment
10. For example, the middle stand off 222 in the center of the
cover segment 10 has a flange 227 extending to the side, while the
flange in the upper middle stand off 222 has a flange 227 extending
in an upward direction. The flanges 227 are for packing and
shipping the cover segments in a stacked position, which will be
discussed in more detail below. The flanges 227 fit into and engage
with an indentation 228 formed into each middle stand off 222.
Accordingly, as the cover segments 10 are stacked for shipping,
each flange 227 engages with corresponding indentation 228.
[0113] The side stand offs 221 have a stepped portion 223 formed
into the pocket thereby forming a second pocket 225. This feature
is also for packing and shipping the cover segments 10 in a stacked
position and will be explained in more detail below. Upon stacking
for shipping, the stepped side corner 224 fits into the pocket 225
in a nested position.
[0114] Similar to other embodiments explained above, the cover
segment 10 of this embodiment includes lateral connectors 251 and
252. Upon assembly, the connector tab 251 fits inside and engages
with the tab receiver 252 to form a mechanical connection. As shown
in FIGS. 32A and 32B, the tab receivers 252 and tab connectors 251
are formed to extend outward with respect to the surface of the
cover 3. As shown in FIG. 31, upon lateral connection of cover
segments 10, only the tab receiver 252 is visible when viewing the
cover 2 from the outside.
[0115] FIG. 33D shows a bottom perspective view of the cover
segment 10. As shown in FIG. 33D, portions of the bottom extension
280 do not extend inward as far as other portions of the bottom
extension 280. For example, a portion denoted at 283 in FIG. 33D,
does not extend as far inward relative to the outer surface of the
cover segment 10 as a middle portion of the bottom extension 280.
Further, on the side support legs 231, the outer rib of the rib
formation 233 is made to be smaller and not extend as far in the
outward direction. In addition, as shown in FIGS. 33A and 33C, each
support leg 230, 231 includes an indentation 234. Upon vertical
connection, the edge of the middle groove 272 slides into and
engages the indentation 234 of the middle support leg 230.
Similarly, upon vertical connection, the edges of the side grooves
271 slide into and engage the indentations 234 of the side support
legs 231, respectively. FIG. 33D also shows that the support legs
230, 231 are set back inwardly due to their formation off the
bottom extension 280.
[0116] FIG. 34B is cross section along the line I-I of a cover
formed of cover segments 10 stacked in the vertical direction shown
in FIG. 34A. FIG. 35 is a detailed view of the connection between
the middle groove 272 of top interconnector 270 and middle support
leg 230. Upon vertical connection of cover segments 10, the support
legs 230, 231 slide into the corresponding grooves 271, 272 in the
top interconnector 272. Accordingly, due to the set back formation
of the support legs relative to outer surface of the cover 3 (shown
in FIG. 33D), when vertically stacked, the support legs 230, 231 of
the upper cover segment 10 are not seen from the outside.
[0117] FIG. 36 is a detailed view of the connection between a side
groove 271 and a side support leg 231. The side groove 271 has two
edges 274 and 275 and the side groove 271 is formed so that one
edge 274 of the side groove 271 is formed deeper into top
interconnector 270 than another edge 275 of the side groove 271.
The support legs 230, 231 sliding into corresponding grooves 272,
271, respectively, also function as a guide for radial alignment of
the cover segments 10 as they are connected in the vertical
direction.
[0118] FIG. 37B is a cross section taken along line I-I of a top
view of the cover of an embodiment of the present invention shown
in FIG. 37A. FIG. 38 is a detailed view of the lateral connector
250 showing the mechanical connection of connector tab 251 and tab
receiver 252. Upon lateral connection of two cover segments, shown
in the cross section view of FIG. 38, for example, the connector
tab 251 fits into the tab receiver 252. As shown in FIG. 38, the
top side 256 of the connector tab 251 abuts the lower surface of
the top concave portion 253 of the tab receiver 252. The outward
facing side 257 of the connector tab 251 abuts the inner surface of
the outward facing side 259 of the tab receiver 252. Further, the
bottom side 258 of the connector tab 251 abuts the upper surface of
the bottom concave portion 255 of the tab receiver 252. A flexible
fastener 54 is shown that is preferably a zip-type tie. The
fastener 54 is placed around the tab receiver 252 and fastened to
maintain the connection of the tab receiver 252 and connector tab
251. The top surface of the top concave portion 253 and bottom
surface of bottom concave portion 255 of the tab receiver 252 guide
the fastener 54 and provides for a notch-type area for the fastener
54 to be placed.
[0119] FIG. 39 is an enlarged partial cross section view of a
middle support leg 230 of an upper cover segment 10 engaging with
the middle groove 272 of a lower cover segment 10, upon stacking
cover segments vertically. As shown, the middle groove 272 abuts
the bottom extension 280 forming a flush and continuous seam where
the upper cover segments and the lower cover segments contact each
other. Further, the middle groove 272 abuts and engages the surface
of the support foot indentation 234 of the middle support leg 230.
The indentation 234 have a corresponding shape so that the top
interconnector 270 abuts and engages the indentation 234 in a flush
manner.
[0120] FIG. 40B is a cross section taken along line I-I of a top
view of the cover 2 shown in FIG. 40A. FIG. 41 is an enlarged
partial cross section view showing top interconnector 270 abutting
bottom extension 280. As described above, the abutment shown
creates a seam around the circumference of the cover when the cover
segments 10 are connected in a vertically and laterally. The top
interconnector 270 abuts and contacts with the top interconnector
270 around the cover 2 in a flush and substantially even manner. As
shown in FIG. 41, a downward extending flange extends downwards
further than a thickness of the top interconnector 270. As
mentioned above, the downward extending flange 281 extends in a
downward direction at essentially a 90.degree. angle with respect
to bottom extension 280. The downward extending flange 281 prevents
outside materials (e.g., snow, ice, dirt, chemicals, particulate)
from getting between the cover 2 and the support column 1 at the
horizontal seam.
[0121] FIG. 42 shows the stacking and nesting features of the cover
segments 10 for delivering the cover segments 10. As noted above,
the middle stand offs 222 have a flange member 227 that extends
outwards from the pocket (stand off). As shown in FIG. 42, the
flange member 227 of the middle stand off 222 fits into the
indentation of another middle stand off 222 when arranged and
oriented correctly. With respect to the side stand offs 221, each
one has a stepped portion 223 thereby forming a smaller pocket 225.
Upon stacking for shipping, the stepped side corner 224 fits into
the pocket 225 when correctly arranged, thereby nesting the side
stand off partially within another. Further, when stacked, as a
result of the nesting features shown in FIG. 42, the top
interconnector 270 and bottom extension 280 are prevented from
being compacted by the cumulative weight of stacked cover segments
10. Therefore, the top interconnector 270 and bottom extension 280
retain their form while stacked so as not be bent or otherwise
deformed by the force of adjacent cover segments in the stacked
position.
[0122] An advantage of the present invention is that after
installing the cover segments 10 to form a cover 2 around a support
column 1, a worker is able to remove one cover segment 10 of the
cover 2 and leave the remaining cover segments installed. FIG. 43
is an illustration of one cover segment 10 removed while the other
cover segments 10 forming the cover remain installed. In other
words, a worker can take one cover segment away from the cover to
inspect the support structure 1, for example, and the remaining
cover segments 10 of the cover 2 are left in a stable condition.
One cover segment 10 may be uninstalled without uninstalling
adjacent or any other cover segments 10 of the cover 2.
[0123] It should be further understood by those skilled in the art
that although the foregoing description has been made on
embodiments of the invention, the invention is not limited thereto
and various changes and modifications may be made without departing
from the spirit of the invention and the scope of the appended
claims.
